Ping-Ke Shih 8ebef59d02 wifi: rtw89: print just once for unknown C2H events
[ Upstream commit 7e1c44fe4c ]

When driver receives new or unknown C2H events, it print out messages
repeatedly once events are received, like

  rtw89_8922ae 0000:81:00.0: PHY c2h class 2 not support

To avoid the thousands of messages, use rtw89_info_once() instead. Also,
print out class/func for unknown (undefined) class.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
